Epiphora - Causes, Treatment & When to See a Doctor

What is Epiphora?

Epiphora, commonly known as watery eyes, refers to the excessive production of tears that result in constant or recurring tearing. While some tearing is normal—helping to lubricate and protect the eyes—epiphora occurs when tears overflow or drain improperly. This condition can affect one or both eyes and may be temporary or chronic. It often stems from issues with the tear drainage system, eye irritation, or underlying medical conditions.

According to the Mayo Clinic, mild epiphora is common and usually harmless. However, persistent or severe cases may indicate a more serious problem requiring medical attention.

Common Causes

Epiphora can arise from a variety of causes. Below are some of the most frequent culprits, as outlined by the CDC and NIH:

• Allergies: Pollen, pet dander, or seasonal allergies can irritate the eyes, triggering excess tearing (Cleveland Clinic, 2023).
• Infections: Conjunctivitis (pink eye) or styes can cause inflammation and increased tearing.
• Blocked Tear Ducts: A common issue in infants, though it can occur in adults due to scarring or injury.
• Dry Eyes: Paradoxically, dry eyes may stimulate overproduction of tears as the body tries to compensate (Healthline, 2022).
• Eye Irritants: Wind, smoke, chemicals, or eyeglasses that rub against the eyes can provoke teary eyes.
• Blepharitis: Inflammation of the eyelid margins, often linked to skin conditions like rosacea.
• Age-Related Changes: Tear duct function tends to decline with age.
• Eyelid Problems: Entropion (inward-turning eyelids) or ectropion (outward-turning eyelids) can irritate the eye.
• Neurological Conditions: Rarely, disorders affecting the trigeminal nerve may disrupt tear regulation.
• Medications: Certain drugs, like eye drops containing preservatives, can cause irritation.

Associated Symptoms

Epiphora often comes with other signs, though they may vary depending on the cause. Common companions include:

• Eye Redness: Inflammation or irritation from the underlying condition.
• Itching or Burning: Often linked to allergies or infections.
• Discharge: Clear, yellow, or greenish discharge may indicate infection.
• Blurred Vision: Excess tears can temporarily obscure vision.
• Foreign Body Sensation: A feeling of something in the eye despite no physical object.
• Chronic Itching: Associated with allergic reactions or blepharitis.

The World Health Organization notes that persistent symptoms should not be ignored, as they may signal an underlying issue requiring treatment.

When to See a Doctor

While occasional tearing is normal, seek medical advice if:

• Tearing Persists for more than a few days despite home care.
• Vision is Impaired, suggesting excessive tears or an infection.
• Pain or Swelling Occurs, which may indicate injury or infection.
• Discharge is Thick or Purulent, signaling conjunctivitis or staph infection.
• You’re a Child or Infant, as blocked ducts are common but should be monitored.
• An Underlying Condition Worsens, such as uncontrolled diabetes or autoimmune diseases.

The National Eye Institute recommends prompt evaluation for sudden, severe symptoms to prevent complications like corneal damage.

Diagnosis

To diagnose epiphora, doctors typically: MedlinePlus

1. Review Medical History: Identify potential triggers like allergies or recent eye injuries.
2. Perform a Physical Exam: Check for inflammation, blockages, or foreign bodies.
3. Assess Tear Production: Use tests like the Schirmer’s strip to measure tear quantity.
4. Evaluate Drainage: Observe or use instruments to check if tears drain properly.
5. Order Tests: Allergy testing, blood work, or imaging (e.g., imaging for blocked ducts) may be necessary.

If an infection is suspected, a sample of discharge might be taken to identify the causative organism.

Treatment Options

Treatment depends on the underlying cause. Options range from home remedies to medical interventions:

Home Remedies

• Warm Compresses: Helps unclog blocked ducts and reduce inflammation.
• Artificial Tears: Over-the-counter lubricants can soothe dry eyes that trigger tearing.
• Avoid Irritants: Stay away from smoke, wind, or allergens.

Medical Treatments

• Allergy Medications: Antihistamines or allergen immunotherapy for allergy-related epiphora.
• Antibiotics: Prescribed for bacterial infections like conjunctivitis.
• Tear Duct Surgery: Procedures to clear obstructions, often for infants or chronic cases.
• Botox Injections: Used in some cases of chronic epiphora caused by overactive lacrimal glands (National Library of Medicine, 2021).
• Eyelid Surgery: Corrects structural issues like entropion or ectropion.

Always follow a doctor’s advice, as improper use of medications (e.g., expired eye drops) can worsen symptoms.

Prevention Tips

While not all epiphora is preventable, these steps can reduce risk:

• Protect Eyes: Wear sunglasses or goggles in windy or smoky environments.
• Manage Allergies: Use air purifiers or avoid pollen-heavy areas during peak seasons.
• Practice Eyelid Hygiene: Clean lids daily to prevent blepharitis.
• Treat Chronic Conditions: Control diabetes or autoimmune diseases to reduce eye complications.
• Remove Makeup Before Sleep: Prevents clogging of tiny glands near the eyes.

Regular eye exams can catch problems early, particularly in older adults or those with a family history of tear duct issues.

Emergency Warning Signs

Immediate medical attention is required if you experience:

• Sudden vision loss or double vision
• Severe eye or facial pain
• Redness with purple-tinted skin (indicating possible blood leakage)
• Signs of meningitis, such as headache or neck stiffness (from rare infections)
• Trauma to the eye or face resulting in persistent tearing

Ignoring these signs could lead to permanent eye damage or systemic complications. Emergency care can prevent life-threatening outcomes.

Conclusion

Epiphora is a common condition with diverse causes, ranging from allergies to structural defects. While mild cases often resolve with simple measures, persistent or severe symptoms warrant professional evaluation. Early intervention can alleviate discomfort and prevent complications. For personalized care, consult a healthcare provider or ophthalmologist.
